Dr. Ziliang Jin received his Ph.D. at the China University of Geosciences, Beijing. His PhD thesis project was to study the genesis of Skarn-type iron deposits, which supply the highest grade iron ores in China. He also worked as a guest scientist in the GeoForschung Zentrum (GFZ) SIMS lab in Potsdam, Germany. Since matrix-matched reference materials are critical for SIMS experiments, he worked on the Cameca IMS 1280HR instrument to develop and characterize reference materials, such as the synthetic glass, synthetic olivine, apatite and calcite. His current research work at ASU focuses on the study of water and hydrogen isotopic compositions in anhydrous minerals from the asteroid Itokawa and ordinary chondrites using the NanoSIMS 50L. The aim is to understand the origin and evolution of water in the first formed planetary bodies, i.e., asteroids, in the early solar system.
Dr. Timothy Hahn received his Ph.D. at Washington University in St. Louis in 2019. His Ph.D. research emphasized comparative planetology among differentiated bodies, including the Moon and Vesta, through photometric investigation of planetary surfaces and sample analysis of representative achondrites (i.e., lunar and HED meteorites). Specifically, his research focused on exploiting “big data” in geological and planetary science through a combination of 1) statistical analysis of compositional data; 2) high performance computing and numerical modeling; and 3) geostatistical analysis of spacecraft-derived datasets. His current research at ASU focuses on using nominally anhydrous minerals (e.g., olivine, pyroxene, and plagioclase) as probes into primordial volatiles in the early Solar System through investigation of achondrite parent body crusts and mantles. Timothy’s research utilizes the Cameca NanoSIMS 50L and Cameca IMS 6f SIMS at ASU. His research will also work to develop high-quality ion implant standards for measuring volatile concentrations and D/H in nominally anhydrous minerals.
Brendan Chapman joined the Center for Isotope Analysis in Fall 2019 after earning his bachelor’s degree in Earth Science with a Planetary Focus from the University of California, Santa Cruz. His research interests include geochemistry and cosmochemistry, planetary exploration, and mineralogy, and his happiest place is looking at meteorites through a microscope of any kind. Brendan’s undergraduate research involved identifying evidence of impact deformation in asteroid parent bodies by EBSD (electron backscatter diffraction) analysis of equilibrated ordinary chondrites. For his Ph.D. research at ASU, Brendan will determine the capacity of NAMs (nominally anhydrous minerals) in Hayabusa samples from asteroid Itokawa and carbonaceous chondrites to store water using the Center for Isotope Analysis’ Cameca NanoSIMS 50L. He will also investigate several key processes that dictate the loss and transport of water in the inner solar system
Zebadiah Teichert – He is a graduate student in SESE and is being co-advised by me and Dr. Lynda Williams, an expert in terrestrial clays. His interest is in using Li and B to trace the aqueous alteration and thermal history of terrestrial shales.
Jack Schulte – He is a junior studying Physics and Astrophysics. He is also a NASA Space Grant recipient (2018-2019). His main interests include stellar and planetary astrophysics, especially the study of presolar grains in meteorites. He is a private pilot and works part-time as an aircraft manager at Scottsdale Airport. He also owns a small reflecting telescope and spends an occasional night observing and photographing the Moon and neighboring planets.
Ethan Duncan – He is a junior majoring in Astrophysics and minoring in Physics. He is a member of Barrett, the Honors College. He is interested in stellar and planetary Astrophysics especially in the formation of exospheres by particle bombardment on planetary surfaces. He has recently been trying his hand at astrophotography with a small refracting telescope on the weekends. He also performs part-time at Jesterz Improv Comedy Club at Mesa Riverview.
Victoria Froh – She is a junior double majoring in Chemistry and Earth and Space Exploration. She is in the Honors College and is a Gammage Scholar through Barrett. She is interested in the chemical origins/evolution of the universe. She is a captain of ASU’s Women’s Rugby team who competes D1 and finished top 16 in the nation in 2018. She is studying micrometeorites from Antarctica and is also designing a new website for my research group.
Thomas Redford – He is sophomore with a major in Math. His interests lie in understanding the formation of organic materials in stellar environments and in meteorites.
High School Student:
Rithvik Musuku is a high-school student from BASIS Chandler. He works in the summers to research optimal ways of handling and mounting tiny (10-100 micron) particles.
Other students associated with CIA:
Kara Brugman – She is a PhD candidate in SESE and studies why volcanoes erupt by investigating diffusion chronometry in clinopyroxenes. Her interest in the field of diffusion chronometry allowed us to work together in developing new protocols for measuring volcanic rocks using the NanoSIMS 50L at ASU.
Hannah Shamloo – She is a PhD candidate in SESE and also does diffusion chronometry of volcanic rocks using the NanoSIMS.
Tyler Quigley – He is a PhD candidate in the School of Life Sciences. He studies honey bees and their blood-brain barrier with the NanoSIMS.
Jonathan Zaloumis – His doctoral research is to determine biogenicity of microdigitate stromatolites, and to understand the potential for sulfate-rich veins as a biosignature in terrestrial rocks as analogs to Martial rocks, using the NanoSIMS.
Melissa Sedlar – She is doing her second project with me on micrometeorites.
